This update fixes several stability and gameplay issues:

• Fixed: Sub-units / Cosmic Powers / hangar slot expansion / cleared node progress could be lost when continuing
• Fixed: CycloneFang's Split Shadow clone would linger after the boss was defeated
• Fixed: Background occasionally dissolved to Act 0 after returning from title
• Fixed: Tutorial pseudo-boss hull collider now respects configured hit zones
• Fixed: Graze ring radius and Y-offset adjustments now properly apply
• Improved: Hitbox overlays accurately match bullet damage tiers
• Added: Procedural fallback sprite for missing boss PNG assets (no more invisible bosses)
